Doug Cutting commented on HDFS-2298:
------------------------------------
For the record, Thrift doesn't support overloading:
http://wiki.apache.org/thrift/FAQ
And, as far as I can tell, Protocol Buffers doesn't either, so Avro is not
alone in this.
If we convert to another RPC system we'll probably implement a wrapper layer
that converts the overloaded calls to and from the service methods. Even then,
this mapping should be as close to 1:1 as possible. Overloading of RPC methods
will create confusion.
